Bring your own container to the butcher counter, deli counter and cheese counter

Eat more whole fruits and vegetables and less prepared/processed food

Buy milk in returnable glass bottles

Find ways to make kitchen staples instead of buying them in a plastic lined tin. Try soaking and cooking dried beans (it's really easy, I promise!), make your own yogurt, tomato sauce, salad dressing, etc. Even try just one of those things.
